摘要： A device is provided with an array of a plurality of phosphor converted light emitting devices (LEDs) that produce broad spectrum light. The phosphor converted LEDs may produce light with different correlated color temperature (CCT) and are covered with an optical element that assists in mixing the light from the LEDs to produce a desired correlated color temperature. The optical element may be bonded to the phosphor converted light emitting devices. The optical element may be a dome mounted over the phosphor converted light emitting devices and filled with an encapsulant.

摘要： A light emitter includes a light-emitting device (LED) die and an optical element over the LED die. The optical element includes a lens, a window element, and a bond at an interface disposed between the lens and the window element. The window element may be a wavelength converting element or an optically flat plate. The window element may be directly bonded or fused to the lens, or the window element may be bonded by one or more intermediate bonding layers to the lens. The bond between the window element and the lens may have a refractive index similar to that of the window element, the lens, or both.

摘要： A semiconductor light emitting device is provided with a separately fabricated wavelength converting element. The wavelength converting element, of e.g., phosphor and glass, is produced in a sheet that is separated into individual wavelength converting elements, which are bonded to light emitting devices. The wavelength converting elements may be grouped and stored according to their wavelength converting properties. The wavelength converting elements may be selectively matched with a semiconductor light emitting device, to produce a desired mixture of primary and secondary light.
